RT Journal Article T1 Evolución hidroquímica en los acuíferos del sector Ksar El Kebir-Larache (Marruecos) T1 Hydrochemical evolution in the aquifers of the Ksar El Kebir-Larache sectors (Morocco) A1 Bouhmadi, B. A1 Benavente Herrera, José A1 Hidalgo Estévez, Mari Carmen AB The synthesis of hydrochemical data obtained in the lower basin of the Loukkos river (Morocco) as well as the results of speciation and mass transfer calculations point out that the main processes which influence the groundwater composition of the study area are: a) the dissolution of calcite, dolomite, gypsum and halite, b) the acquisition ofC02 and c) the Ca/Na exchange with clayey sediments, although some mixing with connate saline waters can't be rejected. Thus, a hydrochemical evolution has been identified from low salinity (less than 0.5 g/l) waters of a Ca-HC03 type to others of 7-2 g/l (eventually a few tens of g/l) and Ca and/or Na-CI type PB Sociedad Geológica de España YR 1998 FD 1998 LK http://hdl.handle.net/10272/10175 UL http://hdl.handle.net/10272/10175 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
